Dance in triple time (5)
I believe the answer is:
waltz
'dance in triple time' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for waltz that I've seen before include "Ballroom dance, originally from Germany" , "Dance in 3/4 time" , "Three-time dance" , "Dance in three-four time" , "Last dance?" .)
